Stainless steel pump flanges Butt welding flange
Description
Butt welding flange, Its primary function is to connect the pipeline and make the pipeline adhere to the excellent sealing function. If there is a problem in a certain section of pipeline, it is convenient to replace a certain section of pipeline. If there is something wrong with the pipeline, it is easy to disassemble and test. It is suitable for the connection of steel pipe with nominal pressure less than 2.5MPa. The sealing surface of flange can be made into smooth type, concave convex type and mortise groove type. Flange not only saves space and reduces weight, but also ensures no leakage at the joint. It has excellent sealing function.

Characteristic
Butt welding flange is divided into thread connection and welding. Low pressure small diameter has threaded flange, high pressure and low pressure large diameter are welded flange, different pressure flange thickness and connecting bolt diameter and quantity are different. According to different levels of pressure, flange gasket also has different information, from low pressure asbestos gasket, high pressure asbestos gasket to metal gasket. Flange connection is easy to use and can accept large pressure. It is mostly used in the case of relatively gentle medium conditions, such as low-pressure non purified compressed air and low-pressure circulating water. Its advantage is that the price is relatively cheap.
